G2: Alternative bioresources and biofuels
In the last years, Alternative Bioresources and Biofuels Team’s (E2) research was focused on 2 important directions: 1. Alternative Bioresources – research activities regarding on use of microalgae for the decontamination of wastewater; the complex use of microalgae for obtaining useful compounds (lipids, antioxidants, biostimulants, phytocatalysts); sustainable biosequestration of GHG in microalgal photosynthetic systems; exploitation of natural resources to obtain food supplements. 2. Biofuels – research activities regarding on the obtaining of third-generation biofuels (aviation biofuels from algal oil) and second-generation biofuels (biodiesel); biogas obtaining; valorisation of by-products from the biodiesel production; ecological solvents from animal or vegetables wastes. Interdisciplinary profile of Alternative Bioresources and Biofuels Team allows to carry out applied research in chemistry field and organic chemistry technologies (non-petrochemical products, organic intermediary, complex biomass refinery), unconventional technologies, ecological technologies and products, chemical and instrumental analysis, technological transfer, consulting, management and execution of national and international research projects.

Energetic efficiency biogas plants improvement by integrated system: biogas-microalgae-biofuels in frame of biorefinery concept (AlgalBiogasConceptEnergy)
Development and demonstration of innovative technologies to optimize the biogas plants by integrating the open ponds for microalgae cultivation using the digestate resulted from anaerobic digestion as a culture medium
Value added products from microalgae biomass applying biorefinery concepts (AlgaeBioef)
By adopting the concept “zero waste”, the project aims to convert the exhausted biomass from active principles into biocarbons with adsorbent properties, which will be tested for the retention of inorganic compounds.
